Same with me.
Got a S10+. Tried installing latest /e/-firmware (1.16) with latest Odin, latest TWRP, and adb sideload and got stuck up at the boot logo like you.
Same discussion in the german /e/-forum.
A german S10+ User found this discussion in the XDA-Forum.
Seems that Samsungs newest firmware makes problems. The solution was to install Samsung’s spanish stock ROM and then to install /e/. Seems it worked.
I didn’t try it yet.
